While slowing down helps, long rides really help. The warmup cycle seems to really run rich, the less warmup cycles you have per tank the better. I just checked my notes from a long ride this summer, 6 days 1700 miles 45.6 MPG and we did not do the speed limit. The EBR did get the best mileage of the group by 2-8 mpg (liter bikes and sport tourers)
